Description

A multi-filter type two-stage rainwater filter

The present invention relates to a multi-stage filter-type two-stage rainwater filter which removes foreign matters contained in rainwater through a multi-filter and quickly removes rainwater.

In order to solve the shortage of water by recycling the rainwater and to efficiently use the insufficient water resources, in the past, rainwater was collected and stored in a storage tank to filter out floating matters or foreign substances contained in the rainwater, However, there is a limit to the filtration of the rainwater so as to prevent the foreign matter from being effectively contained in the storage tank.

That is, since the rainwater collected in the rainwater storage tank in the state of filtering floating matters or foreign matter contained in the rainwater contains a considerable amount of foreign matter, it is necessary to filter the foreign matter once more in order to recycle it, It should be removed.

However, when precipitation of rainwater is required, it takes a lot of time and area, and the lightweight float can not be easily removed even by sedimentation. In order to utilize cleaner rainwater as a heavy waterway, a rainwater filter is used to float the floater. The rainwater filter of the present invention is structurally complicated so that it is limited to the use of the filter, and since the discharge of filtered rainwater is discharged through the bottom surface, the installation of the filter is not easy and the conventional filter adopts the congestion- And the filtration of foreign matter was not easy.

In addition, the filter for filtering foreign matters in the rainwater filter is effective in filtering the foreign matter as the mesh size is smaller, but the rainwater can not pass through the filter quickly, so that a large amount of rainwater can not be treated.

The present invention relates to a filter for filtering rainwater through a multi-filter and using the filter as a water tank, wherein a multi-filter having a narrow upper side and a wide lower side is installed at the center of the filter cylinder, The multifilter is installed in a coupling frame formed on a bottom plate having a predetermined space on the inner bottom of the filtration tube. An inflow pipe is installed on the upper side of the filtration tube so that rainwater flows in a tangential direction to form a vortex, A drain pipe for discharging unfiltered rainwater is installed on the upper side of the bottom plate, and filtered rainwater collected in a lower space of the bottom plate is used as a water tank through a water supply pipe provided laterally of the filter bag.

The multifilter of the present invention is formed in such a manner that the diameter of the upper side is narrower than the diameter of the lower side, the lower side is fixed to the coupling frame and the multifilters are installed in a triple structure in which filters having different gaps are overlapped with each other at regular intervals The gap of the outer filter is the widest and the gap of the inner filter is the narrowest so that the rainwater introduced into the filter case is discharged into the water supply pipe after passing through the multiple filters in the form of a vortex, As shown in FIG.

In the present invention, the three filters constituting the multiple filters are assembled in such a manner that they are overlapped with each other at regular intervals, while maintaining a constant gap between the filter and the filter while making voids of the filters different from each other, Is introduced into the filter bag in the form of a vortex, and the foreign matter is filtered through the multiple filters.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a filtering apparatus having a cylindrical filtration tube and a filtering apparatus for filtering the filtration tube by a lid and forming a bottom plate at a predetermined distance from the bottom of the filtration tube, A hollow space is formed at the center of the bottom plate 30 and a coupling frame 31 is formed to protrude outwardly of the bottom plate 30. The coupling frame 31 is provided with a multi- And the inflow pipe 11 is installed in the tangential direction on the upper side of the filtration tube 10. The rainwater flowing into the inflow pipe 11 has a vortex shape, The rainwater collected at the lower side of the bottom plate 30 after being filtered by the multiple filters 50 is discharged through the water supply pipe 13 and can not pass through the multiple filters 50, The rainwater collected through the discharge pipe 12 is discharged to the outside It constitutes.

The multifilter 50 of the present invention is formed by a filter 51, 52, 53, and a filter 53. The multifilter 50 has a cylindrical shape with a narrower upper diameter and a larger lower diameter, A large number of voids a, b, and c are formed in the filters 51, 52, and 53 to discharge water. The filters 51, 52, ) 53 are piled up in a triple manner and each of the filters 51, 52 and 53 is maintained at a constant interval by using the spacing members 60 and 61, b) Make the size of (c) smaller (a> b> c)

When the rainwater is supplied in the form of a vortex to the inside of the filter case 10, the voids of the multiple filters 50 pass through the other filters 51, 52 and 53, The number of the filters 51, 52, and 53 may be increased or decreased according to the foreign matter contained in the rainwater. However, the air gap a located outside the multiple filters 50 must be located inside (A > b > c), which is larger than the air gap c, which is formed in the filter 50. Meanwhile, the external rainwater flows into the inside of the multiple filter 50 and is discharged outside after the foreign matter is filtered.

The rainwater not filtered by the foreign matter is discharged through the discharge pipe 12 and the rainwater filtered by the multiple filter 50 is discharged through the water supply pipe 13, The filtration process is divided by the bottom plate 30 to obtain rainwater that is not filtered out of the upper part of the bottom plate 30 and the rainwater filtered out from the bottom of the bottom plate 30 is discharged .

The reason for using the multiple filter 50 in the present invention is to effectively filter the rainwater and the foreign matter and to prevent the rainwater from flowing into the filter in the initial stage when the air gap a is narrowed by the wide filter 51, 53, the rainwater is not stagnated and moves quickly. Therefore, even if a large amount of rainwater flows in, it can be effectively treated.

That is, it is possible to treat a large amount of rainwater in a short period of time by filtering the air with a filter having a larger gap than the filter using a filter having a less air gap and then filtering with a filter having a smaller air gap.

The present invention is characterized in that a multifilter 50 is installed in the filter bag 10 while the multifilter 50 is fixed to the filter frame 31 while each of the filters 51, The filters 51, 52, and 53 constituting the multiple filter 50 are formed such that the diameter of the upper side is narrower than the diameter of the lower side so that the constant intervals are maintained with the holding materials 60 and 61 interposed therebetween. do.

When the installation of the multi-filter 50 is completed, the lid 20 is closed. As the inflow pipe 11, the rainwater filled in the external rainwater storage tank is pumped by the pump and connected to the inflow pipe, The rainwater can be directly introduced without using a separate rainwater storage tank, so that irrigation water is introduced into the inflow pipe 11 regardless of the manner in which the rainwater flows.

The water supply pipe 13 is connected to a storage tank for use of dehumidified rainwater, and the discharge pipe 12 is connected to the outside so as to be discharged to the outside.

In the present invention, when the rainwater is introduced into the inflow pipe 11 and the inside of the filtration tube 10 is filled with rainwater, the rainwater is supplied in the form of a vortex, and the rainwater flowing into the inflow pipe 11 flows into the vortex The rainwater is contacted to the multi-filter 50 for a long time, and the foreign matter is quickly filtered.

Since the multiple filters 50 are formed in such a manner that the air gap a of the filter 51 located outside is narrow and the air gap is narrowed toward the inside of the multi-filter 50, foreign matter contained in the rainwater is filtered through the multi- The rainwater which has not been filtered by the multiplex filter 50 is discharged from the upper side of the bottom plate 30 to the outside through the discharge pipe 12 .

Since the multifilter 50 of the present invention is composed of the filter 51 having a wide gap a on the outer side, a large amount of rainwater can be processed, and the rainwater, which is once filtered by the outer filter 51, (c) are sequentially passed through the gradually decreasing filters 52 and 53, and the multi-filter 50 can process a large amount of rainwater in a short time.

That is, the multifilter 50 of the present invention can filter the filters 52 and 53, which have a small amount of voids b and c, after sequentially filtering the void a through the wide filter 51 As a result, compared with the case of filtering rainwater by using a filter having a small gap as in the prior art, the same quality of rainwater as a result of filtering the foreign matter is maintained, but when the multi filter 50 of the present invention is used, A considerable amount of rainwater can be treated as compared with the case of using only a small filter.

Accordingly, the multi-filter 50 of the present invention can process a large amount of rainwater in a short time, and the discharge pipe 12 is not installed on the bottom surface of the filtration tube 10, 10, the installation of the filtration tube 10 is simplified.
